Best substitutes for Soda/Pop?

My mom and I have a big problem with Coca Cola and Ginger Ale and are looking to cut back. What are some of the best substitutes for these drinks?

About an hour ago I bought a case of merryberry flavored sparkling water. I found it to be disgusting. Maybe other flavors will be better but man did I not like it. To the point where I feel like I need to drink juice or water afterwards to get the last bit of taste of it out of my mouth

Obviously water is good but i definitely would prefer something with an actual taste. I plan to try seltzer water with like juice, kombucha sodas and Olipop. Hopefully I love them! Thanks!
